The Excalibur Bi-Retrograde Calendar by Roger Dubuis

This year, Roger Dubuis celebrates its 30th anniversary, and for the occasion, the company pays tribute to its co-founder’s favourite complication: the bi-retrograde display.

This function, previously featured in the Excalibur Grande Complication alongside a dozen other highly complex mechanisms, takes centre stage once again. The Maison has also introduced a less complicated, more classic edition to further honour the bi-retrograde display.

Also referred to as “the ecliptic counters” by the Maison a nod to their elliptical shape and distinctive role in indicating the months and date the design showcases a symmetrical dial layout. Enhanced by refined detailing, it pays homage to the Maison’s early creations from 1996.

Varnish

Varnish

It is a type of coating that is applied as a liquid substance to the visible components of the watch, particularly the dial. The substance dries on the surface of the component to form a glossy and protective layer.

The process of applying varnish to the watch involves carefully preparing the surface, applying multiple layers of varnish, and allowing each layer to dry and cure properly. This creates a durable and long-lasting finish that can withstand daily wear and tear.

Varnish not only enhances the aesthetic appearance of the watch but also provides protection against scratches, moisture, and other environmental factors. It helps preserve the original beauty of the watch and maintain its quality over time.
